The species ascribed to Leonard Jenyns are those collected at the Galápagos by CD (see Fish). CD was evidently interested in the further distribution of other members of the Galápagos genera. In Journal of researches 2d ed., p. 390, he remarked that the Galápagos fish ‘belong to twelve genera, all widely distributed, with the exception of Prionotus, of which the four previously known species live on the eastern side of America.’
